Abstract

The present invention relates to a device for the extracorporeal treatment of blood or plasma, comprising two compartments, one compartment intended for circulating blood or plasma, and one compartment intended for circulating spent liquid, separated by a wet semi-permeable membrane, characterized in that the device has, before and after sterilization, the following technical characteristics: the membrane is impregnated with an aqueous glycerol solution; the aqueous glycerol solution contains from 7% to 15% by weight of glycerol and is free of toxic chemical compounds; the two compartments are purged of the aqueous glycerol solution. The present invention also relates to processes for manufacturing this device.
